2,2,6,6-Tetramethyl-4-piperidinol Chemical Properties,Usage,Production

Chemical Properties

white to slightly beige crystalline powder

Uses

An intermediate in the preparation of Piperidinyloxy free radical derivatives.

Uses

2,2,6,6-tetramethyl-4-piperidinol has been used to study the irradiation of Camptothecin (CPT) in aerated dimethylsulfoxide (DMSO) solution that leads to formation of singlet oxygen.

Synthesis Reference(s)

The Journal of Organic Chemistry, 37, p. 2050, 1972 DOI: 10.1021/jo00977a047

Purification Methods

The piperidine crystallises from water as a hydrate and crystallises from dry ether or *C6H6 as the anhydrous base. The hydrochloride has m 282-284o (from EtOH/H2O), and the formate has m 207o(dec, from EtOH/EtOAc). [Mailey & Day J Org Chem 22 1061 1957, Beilstein 21 I 195, 21 III/IV 146, 21/1 V 159.]
